Subject: Re: ext4 unknown problem

I will compile my kernel with these options, but I have question what to do now. Should I ignore current state (locked journaling proccess) and just sync and reboot? (I have no problem, but I would like to try to investigate current problem if it is possible with my current kernel config).
